Library Description

Library contains generic functions for controlling the waveform and frequency
output of the click board.

Key functions:

  • void waveform_sineOutput(uint32_t f) - Function for setting the sine wave output.
  • void waveform_triangleOutput(uint32_t f) - Function for setting the triangle wave output.
  • void waveform_squareOutput(uint32_t f) - Function for setting the square wave output.

Examples description

The application is composed of the three sections :

  • System Initialization - Initialize the GPIO and communication structures.
  • Application Initialization - Initialization driver init, default configuration and sets first volume.
  • Application Initialization - Initialize the communication interface and configure the click board.
  • Application Task - Predefined characters are inputed from the serial port. Depending on the character sent the signal frequency, waveform or amplitude will be changed.

Additional Functions :

  • uint32_t waveform_aproxFreqcalculation(float freqency) - This function is used to calculate the aproximate value that will be written to the frequency set register.

Other mikroE Libraries used in the example:

  • SPI
  • UART
  • Conversions
  • C_Sring

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
